Description

Technical Field

[0001] This utility model relates to the technical field of sheet material conveying devices, and in particular to a laser-cut sheet material feeding device. Background Technology

[0002] With the continuous improvement of industrial automation, laser cutting equipment has been widely used in the processing of sheet metal. In existing laser cutting production lines, to improve feeding efficiency and reduce manual handling labor, automatic suction cup feeders are typically installed at the front end of the cutting platform. These feeders use vacuum suction cups to pick up the sheet metal to be processed and transport it from the stacking area to the cutting platform, achieving automatic feeding and positioning of the sheet metal, thus facilitating subsequent laser cutting. However, existing suction cup feeders still have certain shortcomings in practical applications. Because sheet metal is prone to dust accumulation, oil contamination, or slight deformation during stacking, transportation, and storage, the presence of dust particles or localized unevenness on the sheet surface significantly affects the sealing effect between the suction cup and the sheet surface, leading to a reduction in vacuum suction force.

[0003] When the suction force decreases, the suction cup is prone to separating from the material during the handling process. This can cause the material to fall off, the feeding to become unstable, and the feeding accuracy to be affected. In severe cases, the material may fall from a height, posing a significant safety hazard. This could not only injure the operator but also damage the equipment structure and cause economic losses. Utility Model Content

[0004] The purpose of this invention is to solve the safety problem caused by the sheet material falling off the suction cup, and to propose a laser cutting sheet material feeding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A laser-cut sheet material feeding device includes a support base capable of moving along the length of a laser cutting machine. A suction cup assembly is installed on one side of the support base. The suction cup assembly includes a support rod capable of driving a vacuum suction cup to move up and down. A hook rake is installed on the outer side of each support rod on the support base. The hook rake is tractively connected to the support rod. The support rod has a first state and a second state. In the first state, the hook rake is away from the bottom of the vacuum suction cup. In the second state, the hook rake is at least partially located below the vacuum suction cup.

[0007] The suction cup assembly includes a power telescopic rod and a first bracket. The power telescopic rod is vertically arranged and its cylinder is fixed to the support base. The first bracket is fixedly connected to the telescopic end of the power telescopic rod in a horizontal direction. Several support rods are installed below the first bracket. The vacuum suction cup is installed at the bottom of the support rods and is connected to a suction device.

[0008] The suction cup assembly includes a reinforcing rib, which is inclined and has one end fixed to the first bracket and the other end fixedly connected to the telescopic end of the power telescopic rod.

[0009] The hook rake includes a welded or integrally formed hook, an extension rod, and a diagonal rod. The support base is fixedly connected to a horizontally arranged second bracket. A connecting rod is fixedly connected to the bottom of the second bracket. A slider is rotatably connected to the bottom of the connecting rod via a second hinge. The slider is slidably connected to the middle of the slide rail of the diagonal rod. The end of the diagonal rod away from the extension rod is rotatably connected to the support rod via a first hinge. In the first state, the hook is away from the bottom of the vacuum suction cup. In the second state, the hook is at least partially located below the vacuum suction cup, and there is a clearance gap between the top surface of the hook and the plate.

[0010] The laser-cut sheet material feeding device proposed in this utility model has the following advantages: by setting a hook rake on the support base and utilizing the transmission connection structure between the hook rake and the support rod, the automatic opening and closing of the hook rake is realized during the suction cup adsorption and release of the sheet material. This structure automatically forms a support underneath when the sheet material is adsorbed and lifted by the suction cup, preventing the sheet material from accidentally falling off.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-5 A laser-cut sheet material feeding device includes a support base 4 that can move along the length of a laser cutting machine. A suction cup assembly is installed on one side of the support base 4. The suction cup assembly includes a support rod 7 that can drive a vacuum suction cup 6 to move up and down. A hook rake 16 is installed on the outer side of each support rod 7 on the support base 4. The hook rake 16 is connected to the support rod 7 in a transmission manner. The support rod 7 has a first state and a second state. In the first state, the hook rake 16 is away from the vacuum suction cup 6. In the second state, the hook rake 16 is at least partially located below the vacuum suction cup 6.

[0019] When this device is working, the support base 4 moves along the length of the laser cutting machine to a position above the material to be removed. The support base 4 is mounted on the existing walking mechanism, which drives the support base 4 to move. The power unit drives the support rod 7 to move downwards, causing the vacuum suction cup 6 to descend and adhere to the upper surface of the material. Figure 2 As shown, when the support rod 7 continues to move downward, it drives the hook rake 16 to move through the linkage mechanism, causing the hook rake 16 to open outward and be in the first state away from the vacuum suction cup 6.

[0020] like Figure 3 As shown, once the vacuum suction cup 6 has firmly attached the plate, the support rod 7 lifts the plate upwards, the linkage mechanism moves in the opposite direction, and the hook rake 16 retracts inwards to the second state. At this point, the hook rake 16 is at least partially located below the vacuum suction cup 6. (Reference) Figure 5 In this way, if the suction force of the vacuum suction cup 6 weakens or the board falls off, the board can be supported by the hook 16 located below, preventing the board from falling further and causing equipment damage or safety accidents.

[0021] refer to Figure 4 The support rod 7 moves downward to release the plate, and the hook rake 16 opens outward again under the drive of the linkage mechanism, returning to the first state.

[0022] By setting a hook rake 16 on the support base 4 and utilizing the transmission connection structure between it and the support rod 7, the automatic opening and closing of the hook rake 16 is realized during the adsorption and release of the sheet material by the suction cup 6. This structure automatically forms a support below when the sheet material is adsorbed and lifted by the suction cup 6, preventing the sheet material from accidentally falling off. The entire operation process can achieve mechanical linkage control without additional driving components. The structure is simple, the operation is reliable, and the safety and stability of the laser cutting feeding process are improved.

[0023] The suction cup assembly includes a power telescopic rod 2 and a first bracket 1. The power telescopic rod 2 is vertically arranged and its cylinder is fixed to the support base 4. The first bracket 1 is fixedly connected to the telescopic end of the power telescopic rod 2 in a horizontal direction. Several support rods 7 are installed below the first bracket 1. Vacuum suction cups 6 are installed at the bottom of the support rods 7 and are connected to the suction device. The suction cup assembly includes a reinforcing rib 5. The reinforcing rib 5 is inclined and one end is fixed to the first bracket 1 and the other end is fixedly connected to the telescopic end of the power telescopic rod 2.

[0024] When the telescopic end of the power telescopic rod 2 moves downward, the first bracket 1, its supporting rod 7, and the vacuum suction cup 6 move downward simultaneously, bringing the vacuum suction cup 6 close to the surface of the material to be removed. At this time, the suction device begins to suction, and the vacuum suction cup 6 uses internal negative pressure to adsorb the material. When the telescopic end of the power telescopic rod 2 moves in the opposite direction, the first bracket 1 drives the supporting rod 7 and the vacuum suction cup 6, along with the adsorbed material, to rise together, thus completing the lifting action of the material. Those skilled in the art can choose appropriate accessories based on common sense, as long as the above functions can be achieved; no specific limitations are made in this document.

[0025] As one embodiment of the hook rake 16, the hook rake 16 includes a hook 10, an extension rod 11, and a diagonal rod 12, which are welded or integrally formed. The hook rake 16 is composed of the hook 10, the extension rod 11, and the diagonal rod 12, and can be manufactured by welding or integral forming. The support base 4 is fixedly connected to a horizontally arranged second bracket 3. The bottom of the second bracket 3 is fixedly connected to a connecting rod 14. The bottom of the connecting rod 14 is rotatably connected to a slider 15 through a second hinge 9. The slider 15 is slidably connected to the middle of the slide rail 13 of the diagonal rod 12. The end of the diagonal rod 12 away from the extension rod 11 is rotatably connected to the support rod 7 through a first hinge 8. In the first state, the hook 10 is away from the bottom of the vacuum suction cup 6. In the second state, the hook 10 is at least partially located below the vacuum suction cup 6, and there is a clearance gap 17 between the top surface of the hook 10 and the plate. The transmission connection between the hook rake 16 and the support rod 7 is achieved through the first hinge 8, the inclined rod 12 and the slider 15. The lifting and lowering movement of the support rod 7 is achieved by the first hinge 8 causing the inclined rod 12 to change angle, and then the opening and closing action of the hook 10 is achieved through the sliding cooperation between the slider 15 and the slide rail 13.

[0026] refer to Figure 2 When the support rod 7 moves downward, it causes the connection point at the first hinge 8 to descend synchronously, and the inclined rod 12 slides along the slide rail 13. Since the slider 15 at the second hinge 9 is constrained by the connecting rod 14, its position is relatively fixed. The movement of the inclined rod 12 causes the extension rod 11 to drive the hook 10 to open outward, thus placing the hook rake 16 in a first state away from the vacuum suction cup 6. At this time, the hook 10 will not interfere with the suction action of the vacuum suction cup 6, ensuring that the suction cup can smoothly adsorb the board material.

[0027] refer to Figure 3When the support rod 7 rises, the first hinge 8 drives the inclined rod 12 to move in the opposite direction, and the slider 15 slides in the opposite direction along the slide rail 13, causing the extension rod 11 to drive the hook 10 to gradually retract inward, and the hook rake 16 then changes to the second state. At this time, the top surface of the hook 10 is at least partially located below the vacuum suction cup 6, forming a lower support structure for the plate.

[0028] refer to Figure 5 If the vacuum suction cup 6 has insufficient suction force and the board accidentally comes loose, the board will be supported by the hook 10 located below, thus preventing the board from falling further.

[0029] refer to Figure 4 When the support rod 7 moves downward again to release the plate, the first hinge 8 drives the inclined rod 12 to slide along the slide rail 13 again, and the hook 10 opens outward again, returning to the first state. During this process, the clearance 17 reserved between the top surface of the hook 10 and the plate ensures that the hook 10 will not interfere with the plate when the suction cup 6 releases the plate downward, thus achieving smooth unloading.

[0030] It should be noted that the "outward opening" of the hook 16 refers to the outward swinging motion of the hook 10 away from the central axis of the vacuum suction cup 6, while the "inward closing" refers to the inward swinging motion of the hook 10 towards the central axis of the vacuum suction cup 6. The clearance 17 is formed by the space between the top surface of the hook 10 and the bottom surface of the plate adsorbed by the vacuum suction cup 6. Its height is slightly greater than 5% to 10% of the plate thickness, which can ensure that the hook 10 will not interfere with the plate during the process of the vacuum suction cup 6 descending to release the plate, and at the same time, it can form a support point in time when the plate falls off. The lifting stroke of the support rod 7 is set to twice the opening and closing stroke of the hook 16. When the support rod 7 descends to the lowest point, the hook 16 is fully opened, and when the support rod 7 rises to the highest point, the hook 16 is fully closed. The entire action process is mutually corresponding and does not interfere with each other.

[0031] The above description is not intended to limit the present technical solution, but rather to enable those skilled in the art to better understand the present solution.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
